Choosing a window air conditioner for an apartment means balancing cooling power with noise, window fit, energy use, and building rules. The right size depends on the room—not just the apartment’s total square footage—and a quiet or smart model may be worth considering if you work or sleep near the unit. These five options range from a compact 6,000-BTU model to a 10,000-BTU U-shaped unit, with one option that also provides supplemental heat.
Before buying, check your lease and measure your window. The coverage figures below come from the supplied product information and are useful starting points, but room layout, sun exposure, and ceiling height can affect how well an AC cools your space.

Our Picks: Best Window Air Conditioners For Apartments reviews
1. Midea EasyCool 6,000 BTU: A Compact Choice for Smaller Rooms
The Midea EasyCool is a straightforward window unit for a bedroom, home office, or other smaller apartment room. Its 6,000-BTU capacity is listed for spaces up to 250 square feet. It offers cooling, fan-only operation, and dehumidifying, so you can choose how to manage comfort when you do not need full cooling.
An LED display and included remote let you adjust the temperature, mode, and timer from across the room. The product information lists a low-mode sound level of 52 dB, plus an Eco mode and an EasyTimer for scheduling. Its reusable, removable filter is designed to catch dust and pet hair; plan to check and clean it as needed.
The stated window range is 23 to 36 inches wide and 14 inches high. That makes measuring especially important in an apartment, where window dimensions and installation rules can vary. The included mounting accessories are a plus, but a screwdriver is not included, and the product information recommends pilot holes for some frames.
Pros:
- Three modes cover cooling, air circulation, and dehumidifying.
- Remote control, Eco mode, and timer add useful convenience.
- Designed for rooms up to 250 square feet.
- Reusable filter can be removed for cleaning.
Cons:
- Its stated coverage is more limited than that of the larger units here.
- Installation requires a screwdriver, which is not included.
Verdict: Choose the EasyCool if you need basic, multi-mode cooling for a smaller room and its window dimensions match your apartment.
2. LG 7,600 BTU Window AC with Heat: Cooling Plus Supplemental Warmth
This LG window unit combines 7,600 BTU of cooling with a supplemental heat option for cooler days. The supplied specifications list coverage up to 330 square feet, placing it between the smaller Midea EasyCool and the larger-capacity choices in this guide. It may suit a medium bedroom or living room where a separate heating mode would be useful.
The unit has two speeds for cooling, heating, and fan operation. LG lists sound levels as low as 52 dB on low mode and includes an auto-restart feature that turns the unit back on after power is restored. Those features can be practical in a room used for sleeping or work, though the published information does not provide a window-size range or detailed installation measurements.
Treat the heat function as supplemental rather than assuming it will replace your apartment’s main heating system. Before choosing this model, check the full listing and installation instructions for window fit, electrical needs, and any heating limitations that matter for your room.
Pros:
- Combines cooling with a supplemental heat option.
- Listed for rooms up to 330 square feet.
- Two speeds are provided for cooling, heating, and fan operation.
- Auto restart restores operation after power returns.

This 10,000-BTU Midea U is the highest-capacity option in this lineup, with stated coverage up to 450 square feet. Its U-shaped design leaves space for the window to open while the unit is installed. Midea also says the window helps block outside noise, and the inverter system is designed to reduce operating noise and vibration. The supplied specifications list operation as low as 32 dBA.
The unit is Wi-Fi enabled and can be controlled through the SmartHome app or compatible Alexa and Google Assistant devices. The product information also describes an anti-theft mechanism that locks the window when it is closed. Its inverter system is promoted for energy savings and is described in the supplied information as ENERGY STAR certified; check the product listing and official certification details if that designation is central to your choice.
Installation uses an included quick-snap bracket and sidearms. The stated fit is for single-hung or double-hung windows 22 to 36 inches wide, with a minimum height of 13.75 inches. The U-shaped format has more specific setup requirements than a basic window unit, so check the window style, sill, clearance, and installation instructions before ordering.
Pros:
- Highest listed capacity and coverage in this group.
- U-shaped design allows the window to open when installed.
- Wi-Fi and voice-assistant compatibility provide remote control options.

DELLA lists a CEER of 10.9, a 54 dB low sound level, and temperature settings from 61°F to 88°F.

- Four modes, three fan speeds, sleep mode, and a 24-hour timer.
- Remote control and app control are included.

- U-shaped design allows the window to open and is intended to limit outside noise.

How to Choose a Window Air Conditioner for an Apartment
Match BTU Capacity to the Room
BTU capacity is a useful starting point when comparing window ACs. The models here range from 6,000 BTU for spaces listed up to 250 square feet to 10,000 BTU for spaces listed up to 450 square feet. Use the room’s size as a guide, then account for conditions such as strong sun, an open-plan layout, or a room that connects to other spaces. A product’s stated coverage is not a guarantee that it will cool every apartment layout equally well.
Measure the Window Before You Order
Measure the usable width and height of the open window, and compare those numbers with the product’s stated range. Also check the window style and sill, since the Midea U models specify single-hung or double-hung windows. The supplied fit information varies by model: the EasyCool lists a 23-to-36-inch width and 14-inch height, while the U-shaped models list a 22-to-36-inch width and 13.75-inch minimum height. Do not assume that two units with similar capacity fit the same opening.
Check Your Lease and Building Rules
Apartment owners and managers may set rules for window units, brackets, exterior appearance, or installation. Ask before buying if your lease or building guidelines are unclear. Check whether the required support bracket is allowed, whether the window can remain secure, and whether installation must be handled by building staff. A unit that fits the opening may still be unsuitable if your building does not allow that installation method.
Consider Noise Where You Sleep or Work
Sound levels can matter when the AC is close to a bed, desk, or living area. The supplied information lists low-mode levels of 52 dB for the Midea EasyCool and LG, 54 dB for the DELLA, and as low as 32 dBA for the Midea U models. These figures are product specifications, and sound can vary with settings and the room. If quieter operation is a priority, compare the listed figures and consider the U-shaped inverter designs.
Decide Whether Smart Controls Are Useful
App and voice controls may help if you want to adjust the unit without reaching for its panel. Both Midea U models support app control and Alexa or Google Assistant, and the DELLA has app control. The EasyCool and LG include remotes, so you can change settings from across the room without relying on Wi-Fi. Choose connected features only if you expect to use them.
Compare Modes and Extra Functions
Cooling is not the only useful setting. Fan mode can circulate air without using the cooling mode, while dehumidifier or Dry mode can help manage humidity. The EasyCool includes cooling, fan, and dehumidifier modes; the DELLA adds Auto, Cool, Fan, and Dry modes; and the LG includes a supplemental heat function. Think about the conditions in your room and select features that solve a real need.
Plan for Installation and Maintenance
Window ACs need a secure installation, and some may require help to lift or position safely. Check whether the required tools are included and read the installation instructions before you start. The EasyCool requires a screwdriver that is not included, while the Midea U models use an included quick-snap bracket. Also check how to remove and clean the filter; the EasyCool’s filter is described as reusable and removable.
Frequently Asked Questions
What size window air conditioner is best for an apartment?
It depends on the room you want to cool, not simply the apartment’s total size. The products here list coverage from 250 to 450 square feet. Measure the room and compare its layout and sun exposure with the manufacturer’s coverage guidance.
Can a window AC cool an entire apartment?
A window unit is generally best suited to the room or connected area within its stated coverage. Walls, doorways, and distance can limit how much cool air reaches other rooms. For better results, choose a unit for the space where you spend the most time and keep its filter clean.
What is different about a U-shaped window air conditioner?
The Midea U models place the window sash within the unit’s U-shaped design. According to the supplied product information, this lets the window open while the AC is installed and helps block outside noise. These models use a specific bracket and require a compatible window, so confirm fit and installation details first.
Do any of these window ACs also provide heat?
The LG 7,600-BTU model includes a supplemental heat option. Its product information describes the feature as a way to add warmth on cooler days, so do not assume it replaces your apartment’s main heating system.
Which models include smart controls?
The Midea U 10,000-BTU and 8,000-BTU models support Wi-Fi control through the SmartHome app and compatibility with Alexa and Google Assistant. The DELLA lists app control through Della+. The EasyCool and LG include remote controls.
Should I check with my landlord before installing a window AC?
Yes, if you rent or live in a building with shared rules. Check your lease and ask the property manager about window units, brackets, exterior changes, and installation requirements before ordering.
Which option is best for a small apartment bedroom?
The Midea EasyCool is the smallest-capacity model in this group and is listed for rooms up to 250 square feet. It may be a good starting point for a smaller bedroom if the window dimensions fit. For a larger room or a preference for smart controls, compare the DELLA or Midea U models.
Final Recommendation
For a smaller apartment room, the Midea EasyCool is a practical pick with three modes and a remote. The Midea U 10,000-BTU model stands out for larger spaces, its U-shaped design, and smart controls, while the LG is the option to consider if supplemental heat matters. Before choosing any model, confirm the room coverage, window measurements, installation requirements, and your building’s rules.
